Changing the developer mix

You need the following items when you change developer mix:

Procedure:

Do this procedure when you see the following message: 0788 Change Developer Mix or 0789 Developer Drain Open.

Note:
You do not have to replace developer mix the first time you see the Change Developer Mix message. To bypass the message, select Check Reset on the touch panel.

The Change Developer Mix message reappears each time end-of-forms is reached, and every 4 000 feet of forms thereafter if you are using a roll-feed preprocessing device. When 50 000 additional feet of forms have been processed since the message originally appeared, you must change developer mix before you can return the printer to Ready status.

Tip:
  1. Open the center front cover, the center top cover, and the right front cover as shown.

  2. Clear the forms, if possible, from directly under the developer mix drain hose at the right side of the forms input area.
  3. Remove the cap from an empty developer mix bottle, and put the bottle in the forms input area, directly under the developer mix drain hose.
  4. Pull out the developer drain hose, keeping the capped end pointing up (so that any developer mix in the hose from the last change does not spill). Remove the cap from the hose.

  5. Carefully insert the end of the hose into the empty developer mix bottle and put the bottle on the floor.
    Note:
    The empty developer mix bottle stays in the machine at all times.
    Ensure that the hose is inserted securely and that no sharp bends obstruct the hose.
    Important:
    1. Never open the developer drain unless the developer drain hose is inserted into an empty developer mix bottle.
    2. After you have opened and closed the developer drain, you must replace the developer mix. Opening the drain resets the developer mix usage timer. Resetting the timer without changing the developer mix could result in severe print quality problems caused by the developer mix being used beyond its normal life.

  8. The developer starts draining the developer mix immediately. Hold the drain hose so that it does not come out of the empty mix bottle. Shake the hose several times while the mix is draining to ensure that no developer mix remains in the hose.
  9. If necessary, press the Developer Run Push Button (R) one time to ensure that all of the developer mix is drained. There should be about 1.8 liters of used developer mix in the bottle.

  11. Once the developer mix has finished draining, ensure that no developer mix remains in the drain hose by shaking the hose vigorously while you hold the hose as vertical as possible.
  12. Remove the developer drain hose from the bottle. Put the cap on the developer drain hose, and return the hose to its recessed storage area

  13. Put the cap on the bottle. Discard the bottle and its contents per local regulations.
    Attention: To prevent print quality problems, never reuse waste developer mix. Never put anything other than developer mix into the developer inlet.
  14. Remove the cap from the new developer mix bottle.
  15. Remove the developer inlet cover.

  17. Ensure that the developer drain is closed.
  18. Press the Developer Run Push Button (R) and slowly pour the developer mix into the inlet. If the developer stops running before the new developer mix bottle is empty, press the Developer Run Push Button (R) again.

  19. Clean the empty developer mix bottle with a cloth or paper towel to remove any excess developer mix. Save the bottle for the next time you change developer mix.
    Tip:
    If you already have several empty developer mix bottles in storage, you may discard the extra bottle per local regulations.
  20. Put the developer inlet cover back in place.
